Synergy Amps today announced the release of the Marshall JMP Preamp Module, developed in partnership with Marshall Amplification. This all-tube, two channel module delivers the unmistakable growl, touch sensitivity, and dynamic response of the legendary JMP - now in a compact, modular format designed for today’s players.
From Eric Clapton and Jimi Hendrix to Jimmy Page, Eddie Van Halen, and Angus Young, the Marshall JMP amps have shaped the sound of rock for generations. With the new Synergy JMP module, guitarists can now harness that iconic Plexi tone at any volume, with the flexibility of Synergy’s modular system.
The JMP has always been about raw energy and expressive touch, and now players can access that authentic tone through the Synergy platform - without compromise.
The JMP module captures every nuance of the classic circuit with the following features:
- Dual 12AX7 preamp tubes for real-tube harmonics.
- Two independent channels with Volume 1, Volume 2, Bass, Middle, Treble, and Master controls.
- 1960s and 1970s voicing switches to replicate era-specific JMP tones.
- Four Bright switches to fine-tune treble response.
- Cathode Select switch for classic input tube configurations.
- An innovative “0-watt power amp” phase inverter design that replicates the feel and dynamics of a cranked Marshall head.
With the Synergy system, players can build their ultimate all-tube rig without sacrificing authenticity with modules from the world’s most coveted amp designers - Friedman, Soldano, Bogner, Fryette Engl, Diezel, Pavey, Dr. Z and now the most famous of them all – Marshall.
